This coil spring returns arm I9 quickly tonormal position, that is resting on shock absorber 5| of extension I8 of member This return movement of arm 19 to normal position forces member l'i downwardly through action of member 38 forcing extension arm 3| that is attached to extension |8 of member downweirdly. This downwardly movement of member pulls part 22 of member 22 downward quickly behind the ball then resting in the end of track l4 forcing the ball into depression 24 of throwing arm I9, track being then flush with the inner end of member Figure 3 shows track [4 flush through the medium of large cog wheel 28 mounted on the shaft 21 and substantially small cog wheel 35 mounted on shaft 32. Cog wheel 33 which is substantially large is also mounted on shaft-32 and transmits motion to the shaft 3? through medium small cog wheel 39 mounted on the shaft 31. Thus it will be seen that due to this construction, rotary movement of the power :Wheel 10, which is substantially slow is transmitted through the various cog wheels to'the sub- .stantially'heavy fly wheel 23, which is rotated rapidly causing "the device to run smoothly.

Rotating arm 42 mounted on shaft 32 is pro- Ivided with a roller 43 that engages member 44 ,Witheaoh revolution. This rotating arm 42. with each complete circle causes throwing arm l9 through medium of members 64, 45, 43 and. 49 to deliver aball into track 25 at the same time that member 26 forces a ball from wheel ID. This arrangement of partswill keep wheel I!) about one fourthrfull of balls at all times.

The shockabsorberl is plainly shown in Figure 5.

It' tends to prevent the dipper end of throwing arm. l9 from rebounding when it falls quickly after delivering a ballito track 25. Part 5| is an enlarged head against which the dipper strikes when, it falls to normal p'ositionrcausing coil "spring 53 to partly closeup so quickly that'slidablymounted weight 52has barely overcome its inertia and started downwardly when it is met by .a-small head on lower end of rod 5W. This weight takes the rebound from the dipper.

. In the operation of the device, the movableball weights II in conjunction with electric motor i2 tend to cause wheel ID to rotate. This movement is transmitted to wheel 23 through the various {cog wheels, causing the'fly wheel'23 to rotate rapidly, its momentum tending to cause smooth running of machine. .When ,the' roller 43 moves lover thejtop curved surface of part 44, the roller 43 engages the member Ht-forcing the same down- "lwardly and causing the arm 45 to which it is securely fastened to swing-downwardly as shown in dotted lines in Figure 2 causing spring 46 *which is attached to arm 15- and to member 49 to swing arm l9 upwardly, whereupon a' ball which 'restsin the recess at the free end of arm I9, is throwninto the track 25 with sufficient force to causeball to go around curve 25 where it gravitate sto wheel Ill. The arm I 9 contacting with coil spring 6| now falls downwardly to its normal position where it contacts with member l8 through shock absorber 5|.

When arm l9 moves upwardly it causes member 38 to describe nearly half circle upwardly releasing pressure on arm 3| allowing spring 20 to raise member I! to a point regulated by adjusting screw 52. Screw 52 and its point of contact with member I! is clearly shown in Figure 2. Now this upward movement of parts 9, 38, I1, I! and 22 results in a ball then in depression 24 of arm l9 being thrown into track 25, releases one of the balls retarded by member 22, blocks other balls in track M with member I l and also raises shoulder ll of member H to further retard the ball released by member 22. 7

Now when arm I 9 is thrown against coil spring 6| it quickly returns to normal position, the dipper end resting on the enlarged head of part 5| in extension I8. This return movement causes member 38 to describe nearly half circle downwardly in its return to normal position forcing ex tension-arm 3! downwardly causing member 22 to descend behind the ball being retarded by shoulder Il forcing said ball into depression 24 of arm l9 also placing downward pointed part 22 of member 22 in the path of followin balls in track [4 and also sinking part |1 flush with the floor face of track l4 allowing following balls to come to rest against off face of part 22 of member 22. I V r V Figure 2 shows base I supported by two blocks one at each end. Block 2 is of solid material,

block 3 is made to look just like block 2 but is hollowed out to form space for motor l2. The base is also hollowed out to form a space for band wheel 18 en shaft 31 and band wheel l2 on motor shaft |2, and grooved out for band 29 alsoindentation for member 4, said member 4 forming a bearing for one end of shaft3l. This is plainly shown on Figure 2 of the drawings.
